You can pick up their power boards for well under AUD$100 and they come with a connected equipment warranty as well[
Those connected equipment warranties are just a marketing gimmick so don't base any particular purchase on them.
They've got so many loopholes that it is very rare that they'll pay out.
Yay, we have a winner comment that beat me to it !
Dear OP: Those 'feel safe' powerboards are a wank mate, especially the ones you listed, it's no surprise they died in the ass, just when you needed them to do what you thought you paid for
Get the plain non 'surge protection' power boards with the overload buttons, AND a separate RCD you can test
or better still, an orange tradie style 4 way cube/brick thingie with a combined RCD and MCB, and read the instructions!
Clipsal, Arlec, HPM, Deta, go for a reputable Brand name that make a decent product, and have lots of money in reserve
in case you have to sue their ass for an occasional faulty POS
that slips through the OS sweatshoppe assembly line.
i.e. Any water, faults or user stupidity will 'usually' trip these devices a LOT better than the 'surge protection' placebo boards
As most snobby, anti-mates rates electrical retailers will shaft you on the price, Bunnings, Mitre 10, or local hardware store are your friends on this,
after wasting time searching on google and wiki for info about surge BS
from clueless keyboard typing turkeys that can't tell a dog from a cat, much less AC or DC,
or what surge, brownout, short or polarity mean for the frustrated aussie home battler that just wants to plug in and get on with it
FWIW: you buy these things once and cry once,
otherwise ignore the above gab and buy same or a better $ $ $ 'surge protection' power boards, if you enjoy crossed finger exercises and crying (NOT! I hope...)
FWIW: there are genuine 'surge' come protection devices out there that will protect your gear pretty much unconditionally,
but you need a healthy credit card to buy one,
and a mate to help carry it to the car and into the man cave
